Top Lock Nuts Useful Information

Lock nuts have to be secured to prevent unintentional loosening. This is done, either by a locking device that engages a keyway in the shaft or key slot in the adapter sleeve, or by a locking mechanism integrated in the nut.
Lock nuts with an integrated locking mechanism reduce the cost of the shaft as no keyway is required. Installation is also quicker and easier because no separate locking device is necessary. However, the loosening torque of these lock nuts requires more attention. For information on loosening torque, refer to the product data sections for the various lock nut series.
The lock nuts listed here constitute the basic SKF assortment. Lock nuts with other locking methods can be supplied on request. For additional information, contact the SKF application engineering service.
